Re: [COFF] What does your "cal" show? (fwd)

Just variation of Earth’s rotational speed over time, AFAIK. http://leapsecond.com/java/gpsclock.htm -- TAI is SI second ticks, UTC is corrected to rotation by leap seconds. Currently they are 37 seconds apart. Adam On Sep 8, 2021, at 6:22 PM, Dave Horsfall <dave(a)horsfall.org> wrote: Ah, leap seconds. I work for an observatory. Some things are in TAI and some are in UTC. At least now I know what to look for when something is 37 seconds off. Isn't about that the transit of the Moon or something? -- Dave_______________________________________________ COFF mailing list COFF(a)minnie.tuhs.org https://minnie.tuhs.org/cgi-bin/mailman/listinfo/coff
